Summer Berry Tart

Serves 8 / This can be assembled up to half a day in advance but is best eaten within a few days.Ingredient tip: Many chefs recommend using currant jam when working with berries, but you can also use apricot or peach jam, or a blend.Serving tip: Excellent when accompanied by caramel-swirl frozen yogurt.

1. With a mixer, beat butter with sugar and salt on medium speed until smooth. Add egg; blend. Add flours and mix until just blended. Shape into a flat disc and wrap in plastic. Refrigerate for at least 2 hours.

2. Remove dough from refrigerator; let rest for 10 minutes. Lightly flour the dough, a working surface, and a rolling pin. Roll dough into a 12-inch circle, about 1/8-inch thick. Fit dough snugly into a 9-inch tart pan with a removable bottom, pressing against the pan bottom and up the sides; trim any overhang. Cover with plastic and refrigerate for an additional 30 minutes, or overnight.

3. Preheat oven to 350°. Unwrap tart shell and bake for 8 minutes, then remove from oven. If sides are collapsing, gently press back into place; prick any air bubbles to deflate. Return shell to oven and bake until golden brown, about 12 more minutes. Let cool on a wire rack, then remove from pan.

4. Heat preserves in a small saucepan until melted. With a pastry brush, coat crust with preserves. Let dry for 45 minutes. In a small bowl, combine yogurt, powdered sugar, and lemon zest. Spread over crust. Arrange fruit over yogurt layer.
